Embodiment 1

[0042] A feed additive for pigs, the added materials and their weight ratios are: Group A: a control group without any additives; Group B: 25% of hawthorn extract, 30% of nano-zinc oxide, and 45% of licorice extract; Kiss extract 10%, hawthorn extract 45%, nano-zinc oxide 45%; Group D: Glycyrrhizae extract 10%, hawthorn extract 25%, nano-zinc oxide 35%, licorice extract 30%; Group E: Glycyrrhizae extract Kiss extract 10%, hawthorn extract 15%, nano zinc oxide 20%, licorice extract 25%, cellulase 30%. The above-mentioned materials are weighed according to the requirements, placed in the mixer, mixed evenly, and the evenly mixed compound feed additive is packed and sealed. Add 2 kg of A-E group additives to 998 kg of complete compound feed for pigs and mix them evenly. Achieved the effect described in the present invention through feeding test. The specific results are as follows:

Abstract

The invention discloses a pig growth-promoting feed additive containing kelp alkaloids and a use method thereof. 30%, licorice extract 5-25%, cellulase 15-35%. Add 2-8wt‰ of additives to every 1000 kg of pig full-price compound feed. The additive is rich in biologically active substances and enzyme preparations, has antibacterial and anti-inflammatory properties, can replace antibiotics, and improve the digestion and utilization rate of pig feed. The invention is characterized in that it can increase the appetite of growing pigs, improve feed digestibility, and promote growth, and is a green and safe feed additive without toxic side effects and drug residues.

Description

technical field [0001] The invention belongs to the field of animal feed additives, and more specifically relates to a feed additive containing gynecine alkaloid for promoting pig growth and a use method thereof. Background technique [0002] With the development of society and economy, the proportion of animal-derived food in the human food structure has increased significantly, and people are paying more and more attention to the safety of animal-derived food. Food safety of animal origin is a major issue related to people's health and national economy and people's livelihood. In order to pursue economic benefits, some illegal drugs such as "lenbuterol" and levadoamine are used in feed, or some antibiotics are abused, resulting in frequent food safety accidents, which are not only harmful to people's food safety, but also harmful to related foods. The export trade has had a serious negative impact. In order to further improve the efficiency of the breeding industry under...
